Master Bond EP30-3LO is a two component epoxy system offering optical clarity, high temperature resistance, and NASA low outgassing approval. This combination of properties enables it to be suitable for bonding, sealing, coating and encapsulation applications in the aerospace, electronics, optical and optoelectronic industries.

This epoxy has a glass transition temperature exceeding 175°C. It also withstands many chemicals, particularly water, oils, acids, bases and solvents over the wide service temperature range of −80°F to +450°F. Often selected for potting applications, EP30-3LO features a low viscosity and reliable electrical insulation values.

With a non-critical 100 to 30 mix ratio by weight, this compound cures with the addition of heat ranging from 250-350°F. As it requires oven curing, EP30-3LO has a long pot life of 6-10 hours at room temperature. It bonds well to a wide variety of substrates including metals, glass, composites and many plastics and rubbers.

EP30-3LO delivers a one year shelf life in its original, unopened containers. It is available in standard packaging ranging from ½ pint to 5 gallon kits.
